- W4294540440 abstract "During the past 5 years, patent ductus arteriosus (PDA) presented in 734 preterm infants (less than 2.5 kg and 37 weeks gestation) of 2,532 admissions (29%). The ductus presented with murmur, bounding pulses, and often congestive heart failure. Medical treatment consisted of the following: fluid restriction, furosemide, respiratory support, and rarely digoxin. The patients who were unresponsive to medical treatment had surgical ligation (306 of 734 or 42%). The patients who had ductal ligation were smaller, i.e., 82% of the surgical patients weighed less than 1.5 kg as compared to 38% of the medical patients. Of those patients weighing less than 1.5 kg, the surgical and medical groups were compared and the following observations made: The incidence of respiratory distress syndrome was greater in the surgical group (86% or 216 of 252 patients versus 69% or 111 of 161 medical patients, p < 0.001) and the long-term survival was better (89% or 224 of 252 surgical patients versus 77% or 124 of 161 medical patients, p < 0.005). In addition, the average duration of intubation was shorter in this surgical subgroup (8.9 versus 13.6 days). Significant left atrial enlargement and echocardiographic left atriallaortic (LA/Ao) ratios of greater than 1.5:1 occurred in 58% or 171 of 290 surgical patients versus 32% or 59 of 190 medical patients (p < 0.001). During the first 3 years of this study (medical treatment averaged 5 days), the duration of intubation in the surgical patients averaged 15.2 days; by comparison, in the last 2 years of this study (medical treatment averaged 1 to 2 days), the duration of intubation was 6.5 days (p < 0.001). Necrotizing enterocolitis (NEC) occurred in 11% or 46 of 428 medical patients versus 0.3% (one of 305 patients) in the ligated group postoperatively (p < 0.001). Late deaths were related to lung disease, central nervous system problems, NEC, and so on. From this study, it was determined that ligation of a significant PDA is associated with (1) zero surgical risk, (2) a reduced incidence of NEC, (3) reduced duration of intubation, especially with early ligation, and (4) improvement in late survival. Thus the surgical approach is our treatment of choice for a refractory PDA." @default.
